Rev. 2 (2026) · published 17 April 2026 doi: 10.21468/SciPostPhysRev.2 pdf BiBTeX RIS Submissions/Reports Abstract We give a systematic theoretical treatment of linear quantum detectors used in modern high energy physics experiments, including dark matter cavity haloscopes, gravitational wave detectors, and impulsive mechanical sensors. We show how to derive the coupling of signals of interest to these devices, and how to calculate noise spectra, signal-to-noise ratios, and detection sensitivities. We emphasize the role of quantum vacuum and thermal noise in these systems. Finally, we review ways in which advanced quantum techniques—squeezing, non-demolition measurements, and entanglement—can be or currently are used to enhance these searches. × TY - JOURPB - SciPost FoundationDO - 10.21468/SciPostPhysRev.2TI - Quantum measurements in fundamental physics: A user’s manualPY - 2026/04/17UR - https://scipost.org/SciPostPhysRev.2JF - SciPost Physics ReviewsJA - SciPost Phys.
